Description-Operation
The 10900 Actuator is a simple powerful mechanical device. It
is Air-to-Extend Stem type. The nominal range of an actuator is
the pressure range in pounds per square inch (psi) in which the
pressure setting can be obtained by adjustment.
Conformation of the diaphragm (11) to the diaphram plate
(10) serves as a flexible upper guide for the actuator stem (6).
Nylon reinforced neoprene diaphragms permit smooth, sensitive
operation. The lower guide is an oil impregnated bronze bushing
(3) located in the spring adjuster (2).
Note: On request, for special services, the nylon reinforced
neoprene diaphragm may be provided with a PTFE coating. Other
materials are optional and available to suit the fluids involved.
The 10900 Series Actuators are designed for use with the 500
Series Regulators for reducing, back pressure and differential
pressure applications.
The opposite chart indicates the combinations available to
provide the desired function. The 10900 Series Actuators are
designated by the nominal range (psi). See the following chart.
In Spring Diaphragm Actuators, three actuator cases are
available: a case rated for 60 psi static pressure, a case rated
for 250 psi static pressure and a case rated for 750 psi static
pressure.
In Differential Pressure Actuators, two actuator cases are
available: a low-pressure case rated for 250 psi static pressure,
and a high-pressure case rated at 600, 1000 and 1500 psi static
pressure.

Installation
On steam service, the regulator should be installed with the
actuator down so that the diaphragm will be protected by a
condensate barrier. If installed otherwise, an adequate
condensate barrier must be incorporated.
In the Spring Diaphragm Actuators, the 1/2” NPT pressure
connection is located on the upper diaphragm case (13).
In the Differential Pressure Actuators, the 1/2” NPT high pressure
connection is located on the upper diaphragm case (13) and the
1/2” NPT low pressure connection is located on the diaphragm
chamber (9) or on the connection adapter (29).
Refer to Regulators Body S/A Instructions for installation
according to the regulator function.
Low Pressure Case Design

Adjustment
When pressure setting has been specified in order, the regulator
is set accordingly at the factory for test. Then, the spring
compression is fully removed to avoid unnecessary stress to
parts (diaphragm, spring) during the stocking.
The regulator pressure range is engraved on the serial plate.
Proceed as follows :
• Open stop valve on the outlet side of the regulator and partially
open stop valve on the inlet side, allowing pressure in the
system to build up slowly.
• Open controlled pressure line valve(s) and check setting by
means of the gauge(s). Set by means of the spring adjuster (2)
of the actuator.
(To increase pressure setting (or pressure differential), turn
adjusting screw clockwise to compress the spring. To decrease
the setting, turn adjusting screw counterclockwise to relieve
spring compression).
• Fully open stop valve on the inlet side of the regulator.
Maintenance
Replacing diaphragm
On Spring Diaphragm Actuators
(500 Series Regulators - Figure 1)
• Remove the controlled pressure line from the diaphragm case
(13) and relieve all spring compression by unscrewing spring
adjuster (2).
• Remove upper diaphragm case (13), [nuts (16) and screws (15)],
[not screws (15) on 150-750 psi range].
a) On 0.5-2 / 1.5-3 / 2-10 / 6-20 / 15-40 / 30-75 / 60-125 and
80-250 psi ranges:
Remove locknut (28), diaphragm washer (14) and diaphragm (11).
b) On 150-750 psi range:
Remove diaphragm (11).
Note: By means of a wrench applied on the plug stem nuts, hold
the actuator stem during this operation.
• Install new diaphragm and reassemble by reversing of the
above description order.
• Readjust the spring compression (see above).
On Differential Actuators
(500-50 Series Regulators - Figure 2)
a. On low pressure case design:
• Remove the high and low pressure lines from the
diaphragm case (13) and the diaphragm chamber (9).
• Relieve all spring compression by unscrewing spring
adjuster (2).
• Remove nuts (16) and cap screws (15). Remove upper
diaphragm case (13).
• Remove locknut (28), upper diaphragm plate (12), upper
O-Ring (25), washer (14) and diaphragm (11).
• Install new diaphragm and reassemble by reversing of
the above description order. Replace upper O-Ring (25) if
necessary.
• Readjust the spring compression (see above).
b. On high pressure case design:
• Remove the high and low pressure lines from the
diaphragm case (13) and the diaphragm chamber (9).
• Relieve all spring compression by uncrewing spring
adjuster (2).
• Remove nuts (16), upper diaphragm case (13) and
diaphragm (11).
• Install new diaphragm and reassemble by reversing of the
above description order.
• Readjust the spring compression (see above).
Replacing O-ring(s) (25)
(low and high pressure case)
On differential actuators, (Figure 2)
• Disassemble the actuator head as described on the
paragraph : “Replacing diaphragm”.
• Remove diaphragm chamber (9) with plunger S/A (24).
• With a wrench applied over O-Ring retainer (26), unscrew it
out of diaphragm chamber (9).
• Remove O-Ring (25), being careful not to damage plunger.
Install new O-Ring, replace and tighten O-Ring retainer (26).
• Reassemble and readjust spring compression.
Uniformly tighten all diaphragm case nuts (16) when
reassembling.
Regulator must be isolated and pressure vented before
disassembly.
It is necessary to proceed with adjustment before servicing.
